    Hi,

    i have a page with two links on it called link1 and link2, when link1 is clicked it creates a cookie called link with the value link1, when link2 is clicked it creates a cookie called link with the value link2. Also when the links are clicked they produce an overlay like light box with the cookie contents echod inside it.

    That all works fine apart from if i click link1 and then close the overlay and click link2 the overlay still displays "link1" instead of displaying "link2" even tho the cookie has updated correctly. See it live HERE and heres the source code im using:

    link.php:

    
<html>
<head>

<style>
		.black_overlay{
			display: none;
			position: absolute;
			top: 0%;
			left: 0%;
			width: 100%;
			height: 100%;
			background-color: black;
			z-index:1001;
			-moz-opacity: 0.8;
			opacity:.80;
			filter: alpha(opacity=80);
		}
		.white_content {
			display: none;
			position: absolute;
			top: 25%;
			left: 25%;
			width: 50%;
			height: 50%;
			padding: 16px;
			border: 16px solid orange;
			background-color: white;
			z-index:1002;
			overflow: auto;
		}
	</style>

<script language="JavaScript">


function lightbox()
		{
		document.getElementById('light').style.display='none';
		document.getElementById('fade').style.display='none';
		<?  $link = $_COOKIE["link"]; ?>
		}
		
function setCookie(c_name,value,expiredays)
{
	var exdate=new Date();
	exdate.setDate(exdate.getDate()+expiredays);
	document.cookie=c_name+ "=" +escape(value)+
	((expiredays==null) ? "" : ";expires="+exdate.toGMTString());

	document.getElementById('light').style.display='block';
	document.getElementById('fade').style.display='block';
}

</script> 
</head>
<body>
<p><a href = "javascript:void(0)" onclick = setCookie('link','link1',365)>Link 1</a></p>
<p><a href = "javascript:void(0)" onclick = setCookie('link','link2',365)>Link 2</a></p>

<div id="divCustomerInfo"><?PHP echo $link;?></div>
<div id="light" class="white_content"><? include('include_me.php'); ?> <a href = "javascript:void(0)" onclick = lightbox()></a></div>
		<div id="fade" class="black_overlay"></div>
		
</body>
</html>
    Code (markup):
    And

    include_me.php

    
<?PHP


$link = $_COOKIE["link"];
echo $link

?>
<html>
<head>


</head>
<a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='none';document.getElementById('fade').style.display='none'">Close</a>

    You have to do it by javascript, not by php. Try it

    link.php

    
<html>
<head>

<style>
		.black_overlay{
			display: none;
			position: absolute;
			top: 0%;
			left: 0%;
			width: 100%;
			height: 100%;
			background-color: black;
			z-index:1001;
			-moz-opacity: 0.8;
			opacity:.80;
			filter: alpha(opacity=80);
		}
		.white_content {
			display: none;
			position: absolute;
			top: 25%;
			left: 25%;
			width: 50%;
			height: 50%;
			padding: 16px;
			border: 16px solid orange;
			background-color: white;
			z-index:1002;
			overflow: auto;
		}
	</style>

<script language="JavaScript">


function lightbox()
		{
		document.getElementById('light').style.display='none';
		document.getElementById('fade').style.display='none';
		}

function setCookie(c_name,value,expiredays)
{
	var exdate=new Date();
	exdate.setDate(exdate.getDate()+expiredays);
	document.cookie=c_name+ "=" +escape(value)+
	((expiredays==null) ? "" : ";expires="+exdate.toGMTString());

    document.getElementById('link_cookie').innerHTML = getCookie('link');

	document.getElementById('light').style.display='block';
	document.getElementById('fade').style.display='block';
}

function getCookie(name){
    if(document.cookie.length>0){
      start = document.cookie.indexOf(name+"=");
      if(start!=-1){
        start = start+name.length+1;
        end = document.cookie.indexOf(";",start);
        if(end==-1){
            end = document.cookie.length;
        }

        return unescape(document.cookie.substring(start,end));
        }
      }
    return "";
}

</script>
</head>
<body>
<p><a href = "javascript:void(0)" onclick = setCookie('link','link1',365)>Link 1</a></p>
<p><a href = "javascript:void(0)" onclick = setCookie('link','link2',365)>Link 2</a></p>
